Microservices Decoded: Unraveling the Benefits, Challenges, and Best Practices for APIs

DZone

In today's fast-paced software development landscape, microservices have emerged as a popular architectural pattern. But what exactly are microservices? In a nutshell, microservices are a way of structuring an application as a collection of loosely coupled, fine-grained services that communicate through lightweight protocols. This architectural style enables teams to develop and deploy services independently, offering flexibility and scalability to the software development process.

MySQL Connection Security With Connection Control Plugins

Percona

As a database administrator, have you ever been in a situation when your database confronted a brute force attack? A brute force attack can be launched against a user account in MySQL. MySQL replies with success or error based on supplied credentials, and the time required for the verification is almost the same in either case. Hence, an attacker can launch a brute force attack against a MySQL user account at a rapid rate and can try many different passwords.

Proof of Concept: Horizontal Write Scaling for MySQL With Kubernetes Operator

Percona

Historically MySQL is great in horizontal READ scale. The scaling, in that case, is offered by the different number of Replica nodes, no matter if using standard asynchronous replication or synchronous replication. However, those solutions do not offer the same level of scaling for writes operation. Why? Because the solutions still rely on writing in one single node that works as Primary.
